Abstract (en)
A process for the hydrogenation of carboxylic acid derivatives such as carboxylic acid anhydrides or alkylidene dicarboxylates is provided. The catalyst used to effect the hydrogenation process comprises (1) a Group VIII metal catalyst e.g. ruthenium or rhodium, in the metallic state and (2) a strong acid promoter. The process is useful for hydrogenating acetic anhydride, propionic anhydride and ethylidene diacetate.
